About the Handgun:
The P22 is an identical, but smaller .22LR caliber version of Walther's 9mm Model P99 pistol. Like the P99, it is a polymer frame, double-action (DA/SA), semi-automatic pistol. Unlike the P99, it is hammer-fired and utilizes a fixed barrel, straight blowback operation, as do most .22LR caliber pistols. The safety and magazine release controls are ambidextrous. The frame includes an integrated accessory rail and the grip has interchangeable palmswells.
About the Manufacturer:
Founded in 1886 by Carl Walther, this German company originally manufactured hunting and target rifles. It was not until 1908 that, under the initiative of Fritz Walther, the oldest son of Carl Walther, they began to make pistols. In 1929 they began to make the popular 'police pistols' or PP models. This was followed in 1931 by the first of the PPKs (Polizeipistole, Kriminalmodell). In 1938 the German Reich awarded Walther the contract to produce the 9mm P38 service pistol. After World War II, Walther was reduced to just a collection of designs and patents. But Fritz Walther started anew and began manufacturing in Ulm in southern Germany. The company resumed production of the P38 (renamed as the P1) in 1957 in order to equip the new West German Army, the Bundeswehr, with sidearms. In 1993 the Walther firm was acquired by Umarex of Arnsberg, who continued to manufacture under the Walther name in Ulm and Arnsberg. In 1999, Smith & Wesson and Walther announced a joint plan to distribute Walther branded firearms and accessories in the United States under the name Walther America.
About the Cartridge:
The Stevens Arms Co. developed the .22 Long Rifle rimfire cartridge from the .22 Long cartridge case developed 16 years earlier, with a 40 grain round nose bullet loaded to a higher velocity than the older 29 grain .22 Long bullet. Modern .22 Long Rifle High Velocity cartridges drive a 40 grain copper-plated bullet at a muzzle velocity of 1255 fps and muzzle energy of 140 ft-lbs from a rifle barrel. This rimfire cartridge has become the most popular sporting and target shooting cartridge in the world.
